People became the fastest billionaires in the shortest amount of time
Jay Walker – 1 year
Joining the billionaire club at breakneck speed, entrepreneur and inventor Jay Walker boasted a net worth of $1.8 billion (£1.3bn) in the early part of 2000, just a year after he founded discount offers website Priceline.com. Then the dotcom bust happened. The crash hammered the Priceline.com share price and Walker's net worth had fallen to a mere $333 million (£259m) by October 2000.
